View Full Version : gain or not gain or contrast

September 16, 2005, 17:15:16
hello folks,

i have a Teli CS 8850DIF camera and use vc++6.
when i ask the Grabber class via

bool res = Grabber->isPropertyAvailableWithCurDev(VideoProcAmp_Gain);

its return false. The camera has definitive gain settings.
When i use instead "VideoProcAmp_Contrast" then its return true. The camera has definitive no contrast settings. When i list the avaible properties via "Grabber->getAvailableVCDProperties->getItems()" then i get the right properties, in this case "Gain" and not "Contrast"

Where is the failure or the bug?
Is the "VideoProcAmpProperty" enumeration not correct or the "IC ... library" or the camera driver?
Has anyone the same problems or any idea?

Thanks Stefan
